Why does car buck hesitate when it's cold
 

I have a 89 Gt and it bucks at a steady throttle when it is cold outside. Runsperfect when in neutral. Will run fine if temperature is over 55 or so. The car has a low temp thermostat, I am thinking around a 160. If anyone has suggestions/ideas, I would greatly appreciate them.
Thanks

No sh#t about it running when the motor is cold. I am talking aboutwhen the car isat normal operating temperature. For example,after driving 30 minutes on the interstate it might start hesitating. Thanks 4 the smart Ass comments by the way!

could be the MAF getting thrown off by the denser air, or something MAF related

Hey i have the same problem, Car temp. is about 160 or so and still climbing but it cuts out and "bucks", as you'd say,even when im running like a half atank., but once it is at 190 itdoesnt do it. I'm gonna try a bottle of Heet though, i think its water in the gas, ill let you guys know if i still have any problems....

I thought the density of the air doesnt matter for a maf caus edoesnt it just measure the speed of the air? i kno that hte speed denstiy systems love dense air but idk

run 3 gallons of racing fuel through it..i bet it doesnt do it again, btw over 60% of engine wear comes from driving you car at a below operating temp range.
